The Elder Scrolls V: Skyrim — Dawnguard is the first official add-on for the action role-playing open world video game The Elder Scrolls V: Skyrim. The game was developed by Bethesda Game Studios and published by Bethesda Softworks. The Xbox 360 version of Dawnguard launched in English-speaking territories on 26 June 2012, and in France, Germany, Italy and Spain in mid-July 2012. It was released on Windows (via Steam) on 2 August 2012. Due to performance issues, the PlayStation 3 version of Dawnguard had been delayed indefinitely, and Bethesda had expressed concern that future Skyrim downloadable content may not be available for the system. On January 18, 2013, Bethesda announced that all three DLC expansions would be released on the PlayStation 3 during February 2013.[1][2]
Dawnguard revolves around an ancient prophecy predicted by an Elder Scroll. The Dawnguard, an organisation dedicated to hunting Vampires, are reformed to attempt to stop the return of a powerful clan of Vampires named the Volkihar. The Volkihar’s leader, Lord Harkon, intends to use an Elder Scroll to permanently blot out the sun. The player can choose whether to aid the Dawnguard, or join the Vampires, becoming a Vampire Lord themselves in the process. – Wikipedia (https://en.wikipedia.org/wiki/The_Elder_Scrolls_V:_Skyrim_%E2%80%93_Dawnguard)
